5. Make sure that the cuff edge falls within the range of the <-> mark. If it does
not, use a larger or smaller cuff that will fit better.
6. The limb chosen for taking the measurement should be placed at the same level
as the patient's heart. If this is not possible, use the following method to correct
the measurement result:
„ If the cuff is placed higher than the heart level, add 0.75 mmHg (0.10 kPa) for
each centimeter of difference.
„ If it is placed lower than the heart level, deduct 0.75 mmHg (0.10 kPa) for each
centimeter of difference.
WARNING
z
The width of the cuff should be either 40% of the limb circumference
(50% for neonates) or 2/3 of the upper arm length. The inflatable part of
the cuff should be long enough to circle 50-80% of the limb. The wrong
size cuff can cause erroneous readings. If the cuff size is in question,
use a larger cuff.
z
Do not apply the cuff to a limb that has an intravenous infusion or
catheter in place. This could cause tissue damage around the catheter
when infusion is slowed or blocked during cuff inflation.
z
Make sure the air tubing connecting the blood pressure monitor is not
blocked, twisted, or tangled.
